Abstract (en)

The method includes the following stages: - prepare a pile of laminations each comprising films of anode, polymer electrolyte, cathode and collector and finally an insulating film, and; - cut the assembly produced in a pre-determined form using mechanical means. The piles are prepared in conditions which enable a substantially sealed, rigid, monobloc assembly to be formed, in which all the films adhere to each other. the mechanical cutting operation is carried out without macroscopic deformation of the films forming the assembly and without forming short circuits nor weak points. Cutting is done using mechanical localized abrasives, or a fluid jet containing an solid abrasive.
